Independent testing by Deutsche Telekom verifies this. The combination of Push-in Technology and RJ45 jacks enables quick and easy installation. Easy to snap onto the DIN rail in the control cabinet and can be quickly mounted on a level surface or a perfboard in the control cabinet (multimedia panel). In addition to providing protection against surge voltages, the DT-TELE-WM surge protective device also protects against incorrect installation. An integrated disconnect mechanism and electronic current limiters thus also protect the modem against overcurrents or miswiring. Surge damage caused by thunderstorms can be prevented if all devices at risk are wired with protective devices. Power supplies for extreme ambient conditions The third generation of power supplies sets a new standard in machine building. The power supplies are compact, robust, reliable, and impress with their easy handling. With the protectivecoated PCB, the new power supply ensures high system availability, even under extreme ambient conditions. The coating protects against dust, corrosive gases, and humidity. Failures due to creepage currents and electrochemical migration caused by corrosion are also prevented. The new Trio Power power supplies save space due to their narrow overall width and capability of being mounted directly side by side. The low overall depth enables installation in 125 mm small housings. The power supply units also enable particularly easy handling: The new third generation Trio Power power supply is now available for the first time with a protective coating on the PCB. This enables reliable use, even under extreme ambient conditions. The new DT-TELE-WM-RJ45-PT-I surge protective device from Phoenix Contact is ideal for protecting telecommunication end devices. Push-in connection technology allows for quick and tool-free installation. Integrated marking fields can be used for easy EID and circuit marking. Due to an intuitive commissioning concept, the devices are quickly ready for use. The mechanical lock of the potentiometers ensures that the devices are also tamper-proof. Furthermore, the power supplies feature smart diagnostic options. The multicolor LEDs and a collective relay contact are used to signal all relevant states, such as DC OK, overload, and short circuit. The dynamic boost (150 percent/5 seconds) also enables difficult loads to be started. With the powerful output characteristic curve, even capacitive loads up to 960 W output power in 1 AC and 3 AC can be charged without any problems.
